GEORGE W. JACQUES, OF NEW BEDFORD, MASSACHUSETTS, ASSIGNOR T0 ATLAS TACKoonrona'rron, NEW YORK OF FATEI'LAVEN, IvIASSACI-IUSETTS, A CORPORATIONOF TOP GAUGE MECHANI$M FOR FASTENER-SETTING- MACHINES Application filedJuly 23,

This invention relates to top gauges more especially adapted forfastener setting machines for setting fasteners in shoe uppers and withparticular relation to lacing stud setting machines in which a sectionof reinforcing tape is fixed by the studs to the shoe upper. The topgauge is used to determine the proper position of the shoe upperlengthwise of the line of fasteners so that the uppermost of the serieswill be positioned at the desired distance from the top edge of theupper when set.

' As shoe uppers vary in size, it is apparent that the top gauge must bemovable in order to properlycooperate therewith, and also that thespacing of the studs and the length of tape section to be fixed therebyshould be varied accordingly.

In the present invention, therefore, the stud spacing mechanism hasconnected thereto mechanism by which the top gauge and the tape cuttingmechanism are moved simultaneously therewith so that the threeadjustments are properly coordinated without particular attention on thepart of the operator.

The edges of shoe uppers are commonly finishedby skiving and foldingover and cementing the skived portions, and it is sometimes desired tofix the studs before and sometimes after the folding operation. lVhenthe setting is done before the edge folding, it is evident that thestuds are set further from'the edge of the work than when the folding isdone first, and the top gauge which also serves as an edge gauge shouldbe differently set for the different sequences of operation.

A further feature of this invention, therefore, resides in a gaugehaving a plurality of work engaging elements each adapted to cooperatewith work having one certain width of margin outwardly of the line ofstuds to be set in the work.

For a more complete understanding of this invention together withfurther objects and advantageous details and combinations of parts,reference may be had to the accompanying drawings in which Figure l is afragmentary front elevation 1925. Serial No. 45,636.

of a stud setting machine showing the subject matter of the presentinvention.

Figure 2 is a side elevation of a portionof the same.

Figure 3 is a detail perspective of the top gauge and its immediatemounting, parts being broken away.

Figure 4 is a detail in perspective showing the gauge in operativerelation to the folded edge of a shoe upper.

Fi ure 5 is a similar view showing-the gauge in a different adjustedposition cooperating with the unfolded edge of a .shoe upper.

Figures 6 and 7 illustrate tape sections of y i the same length, buthaving four and three studs, respectively, set therein in series.

Referring to these drawings, at 1 is indicated a stud spacing adjustingclever, this lever being fulcrumed at 2 on a frame member 3 and having atoothed portion 4 thereon meshing with a gear segment 5 on one arm of abell crank rock lever 6. This rock lever 6 is fulcrumed at 7 and its arm8 is pivoted at 9 to a link 10 which extends tothe stud spacingmechanism and may correspond to the link connecting the members 0 and 0shown in Figure 7 of the Glass Patent No. 811,839 granted February 6,1905 for Machines for setting lacing hooks or studs. At 20 is shown aslidecarrying a portion of the stud setting mechanism comprising a punchand set 21 which is adapted to punch a piece of work lying on the worktable 22 and then carry it into the position shown in Figure 1 above astud presenting and cooperating set ting mechanism 23.

In the particular mechanism shown, in parallel relation to the worktable 22 is a guide bar 24 on which is slidable a tape .feedin andcutting mechanism 25. This may be of any suitable type, but as hereinshown is the block 27. As shown this knife is actuated through a lever29 which is rocked at suitable times by means of the movement of a slidebar 32 having a wedge shaped end 30 which engages beneath the rear endof the lever 29. The particular manner in which this motion is effectedis immaterial to the present invention, but is fully disclosed in theapplication hereinbefore referred to. This block 27, together with theknife 28, is slidable along the bar 24 to determine the distance of theknife from the punch and set 21, and thus to determine the length of thetape section to be fixed by the studs to the work. Adjustment of thisblock to determine this length is effected automatically at the sametime as the spacing adjustment of the studs is effected, and for thispurpose a link extends from the pivot 9 to a rocker 41 to which isoperatively connected a rocker 42 from which extends a link 43 to theblock 27. This mechanism is also shown and claimed in the applicationhereinbefore referred to.

The rock lever 6 has fixed thereto a cam roller which rides in a camslot 51 in a plate 52 which is secured to the upper end of an arm 53fixed to a rock shaft 54. This rock fulcrumed at on a frame yoke piece61,

the upper laterally turned end of which furnishes a bearing support forthe rockers 41 and 42. As shown best in Figure 3 the outer free end ofthe link 59 is slotted as at 161 and in this slot rides a guide pin 62projecting from a rod 64 housed within a sleeve member 65. The sleevemember 65 has a slot through its lower portion as at 66 for the passageof the pin 62. Within the sleeve 65 and surrounding the rod 64is aspring 67 reacting between a collar 68 fixed to the rod 64 and ashoulder adjacent to the opposite end of the sleeve 65 by which meansthe rod 64 is normally held with the pin 62 adjacent to one end thereof.The opposite end of the rod 64 projecting through the sleeve carries adepending pin 70 to the lower end of which is fixed a flat plate 71carrying the top gauge 72. "When the handle Iis rocked to change thespacing of the studs and to change the length of tape section to befixed by the studs to the material, the rock shaft 54 is also caused torock by the riding of the roller within the cam slot 51 and the arm 56is thereupon moved to cause its cam head 57 to act on the roller 58 toswing the link 59 and thus to advance and retract the rod 64 carryingthe top gauge. The roller 58 is held in engagement with the cam head 57by means such as a spring 75 fixed at one end as at 76 to the link 59and at its other end to a pin 77 on which the roller 50 is journaled. Itwill thus be seen that the rocking of the handle 1 acts simultaneouslyto adjust the spacing of the studs, the length of the tape section whichis to be made fast by a series of such studs to the work, and the topgauge which determines the setting of the first eyelet of the series inthe work, and likewise determines the distance in from the edge of thework at which the row of studs will be fixed.

The top gauge engages the work as. illustrated in Figures 4 and 5, inFigure 4 the work edge being shown as skived and folded over andcemented in place, whereas in Figure 5 the skiving has been effected butthe folding has not yet been accomplished. In order that the studs shallbe at the same distance from the edge of the work whether the folding isaccomplished before or after the setting of the studs, it is necessarythat the top gauge should be correspondingly adjusted. For this purposethe top gauge 72, as shown best in Figures 4 and 5, is formed as anangle piece having a relatively long arm 80 and a relatively short arm81, either of which maybe presented so that the work may contact withits end face. The gauge 7 2 is pivoted on a screw 82- to the plate 71,the gauge as shown being slotted at 83 and the plate passing therein. Inorder to hold the gauge in either one of its adjusted positions, it isshown as provided with a pair of notches 84 on its under face witheither of which may be selectively engaged a spring 85, fixed at oneend, as by a screw 86, to the plate 71. When the longer arm 80 of thegauge is presented in substan tial alinement with the plate 85 the workmay contact with its rounded end, as shown in Figure 4, this longer armof the gauge being used when the folding of the edge of the work hasbeen completed. When it is desired to set the studs before thefoldinghas been accomplished, the gauge 7 2 is turned about its pivot until thearm 81 is in substantial alinement with the plate 71, whereupon theouter rounded end of this shorter arm engages the work. The differencein length between the longer arm and the shorter arm of the top gauge isequal to the amount of stock which is folded back when the edge foldingoperation is accomplished so that whether the edge folding is done afterthe stud setting or before, the distance from the edge of the finishedupper at which the studs are placed is the same provided the properportion of the top gauge has been presented thereto. The gauge is thusadjustable for top gauging by the translator-y movement resulting fromthe advance or retraction of the rod 64 when the handle 1 is rocked orwhen the screw 88 is adjusted as hereinafter described, and it isadditionally adjustable by rotation so that the translatory adjustmentmay be accurate for different spacings of the fasteners from the workedge with which the gauge may be contacted.

Commonly four studs are set in each series, as shown in Figure 6, butsometimes it is desired to set only three, as shown in Figure 7, andunder these conditions the length of tape section and the size of theupper being unchanged, it is necessary to increase the spacing of thestuds. As, however, with the construction heretofore described, increaseof such spacing would automatically increase the gauge setting and thelengths of tape section in accordance with the requirements for fourstuds at the increased spacing, provision is made by which the length oftape section and the position of the top gauge may be made the same asbefore. For this purpose the arm 56 may be made angularly adjustableabout the shaft 54, as shown in Figures 2 and 3, in which a collar 85 isclamped to the rock shaft 54: and is provided with a portion 86extending lengthwise of this shaft. Through the extension 87 of the arm56 is threaded an adjusting screw 88 the end of which bears against theportion 86. When three studs are to be set in series the spacing leveris turned to adjust the work feeding parts to the required condition,the top gauge and tape guide moving to correspond, and then bymanipulation of the adjusting screw 88, the top gauge and the tapecutting guide are re turned to their former positions corresponding tothe size of upper in which the three studs are to be set. Thus the topgauge is adjustable in accordance with the length of the line offasteners to be set, having due regard to both their spacing from oneanother and to their number, and it is also adjustable in accordancewith the spacing of the fasteners from the edge of the work, whichdepends on whether the edge folding has or has not been done at the timethe fastenings are set.

Having thus described an embodiment of this invention it should beevident to those skilled in the art that various changes andmodifications might be made therein without departing from its spirit orscope as defined by the appended claims.
